DESCRIPTION
Select this option to have the NBG420N switch to bridge mode automatically
when the NBG420N gets a WAN IP address in the range of 192.168.x.y
(where x and y are from zero to nine) no matter what the LAN IP address is.
This might happen if you put the NBG420N behind a NAT router that assigns
it this IP address. When the NBG420N is in bridge mode, the NBG420N acts
as an AP and all the interfaces (LAN, WAN and WLAN) are bridged. In this
mode, your NAT, DHCP server, firewall and bandwidth management (rules)
on the NBG420N are not available. You do not have to reconfigure them if
you return to router mode.
Note: The NBG420N automatically turns back to Router Mode
when the NBG420N gets a WAN IP address that is not in
the 192.168.x.y range.
Auto-bridging only works under the following conditions:
• The WAN IP must be 192.168.x.y (where x and y must be from zero to
nine). If the LAN IP address and the WAN IP address are in the same
subnet but x or y is greater than nine, the device operates in router mode
(with firewall and bandwidth management available).
• The device must be in Router Mode (see
more information) for auto-bridging to become active.
Click Apply to save your changes back to the NBG420N.
